Have brand new manual did put new coil on new plug premium fuel

[chrs]

Any other ideas

[muthey]

try going back to low grade fuel, have to remember these were made before premium was an option, also have you tried cleaning the carb, could have got something in it that's plugging it up after a certain time

[chrs]

Carb was cleaned a week ago have dumped 800 in to getting this done with no result.

[chrs]

If it was a Carb it would plug any time not ager 5 min of riding right

[muthey]

I guess unplug cdi and test it with a good ohm meter according to the manual

[chrs]

Yea maby c were it reads at and maby stator
